; The'present invention relates to a "non-skid driving apparatus" for-use on automobiles, trucks and the like andhas for its prime object toprovide; means which maybe brought into action 5 quickly, to prevent skidding-of the automobile or slipping of the wheels on ice, andu'nderlikev V i v V a} I i I x r being. slidableatherein andadj'ustable by [a f double ended and oppositely threadedbolt 23 ma, 1, 5 a

manner more clearly illustrated. in l-Figure 10. 65 transverse-channel foot-'25 with a plurality of,

conditions.- I I A still further -very important object of the invention resides' in theprovision of an appara-. tus of this nature whichis exceedingly simplein its construction, strong andgdurable, convenient,

thoroughly efiicient and reliablein use and opera- .tion, andotherwisefwell adapted to thepurpose for which it is designed." l I With the 3 above and numerous other objects in view as will appear as the description pro: ceeds, the invention resides in certain noveljfeatures of construction, and in .the combination and arrangement of parts as willbe hereinafter more In the drawings:

and -8 respectively. The sprocket 5 is formed fat onefedge' with an inwardly directed annular flange 9,:having apertured ears. projecting in; r 1 wardly, 'therefrom to be boltedas' at 11 to a rear "in the slots or of the'appara Figure 4 is a sectional elevational view of one of through a wheel showing another form of ative positionseparately by manipulation of the wheel The sprocket isl formed ona plate 14 adapted to be boltedatl5 about a hub lfi of 1 a rear wheel .17.

ranged pair's oi -links 31' pivoted thereto by .pins

, 32 and the links '31 have cross cleats 33. mounted thereon and are, formed with inwardly directed .cleats 35. ifhecleats35 are adapted for projection. p in s 7. -8 and to straddle the 75 rollers. .g V v i "Rods 37 are 'pivotallyengaged with the upper v j, ends of thearrns 21 and are engaged with cranks '33 on the sections of ashaft 39"journalled across the. frame" 40fo f thefautomobilej The spring or 80 springs 41 tend to, pushthe rods 37 rearwardly Figure 3 is a sectional view through "the. rear 5 axle showinga'rear wheel in elevationvwith the so as .to swing the arms forwardly and upwardly '1 in a non-engaging position. The shaftSQ'is di'- I vided into two 'alined sections which operate in-;

dependently of each other and which are hollow' with a rod 42 projecting in'the inner ends there of. Cranks'43 are mounted on thejinner ends] of'the shaft sections-and have rods 44 connected 1 thereto and leading. forwardly andsconnectedito the lower ends of handlevers-45. Stops 46, are 9;

mounted on intermediate portions of the rods 44. j

.The rods 44 extend through af plate l7 to the 1 rear of the stops 46 and formed with a notch '48 through which extends -a rod 49 leading forwardly. therefrom and engaged with the brake, 91

pedal 50. stop 51 on the rear end of the rodff l i I 149 is, adapted to engage the: plate 47. fl his stop, Figure 10 is a fragmentary perspective view of '51. may be lifted up by acatch 52 so 'as'to'make' the foot pedal 50 inoperative if so desired.

f From ,the above detailed description it will be' readily appreciated thatvupon depression of the foot lever 50, the rods 37 willcbe caused to 'move forwardly so as toswing the" arms 2 1 downwardlyand rearwardly to the position shown ,'in' Figure 3 so thatthe chains engage the snow covered ground or the like to prevent skidding and slipping of "the wheel. v I .1Eitheri of thechains' aybe actuated to opera proper hand lever jaswill be quite. apparent.

I It is thought that the construction, operation,

v utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detaileddescription.

g The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification sincein actual practice it attains the features of advantage I I enumerated as desirable in the statement of the 1 invention and the above description.

It will be, apparent that changes in the details of construction, and in the combination and. ar-- rangementof parts may be resorted to without departing from the spirit or scope of the invention'as hereinafter claimed or: sacrificing any of its advantages.

Having thus described niy intention what I claim as new is:

1. In combination with a pairiof-rearwheels of 7 a vehicle, a frame and an axle housing, a sprocket wheel; a chain trained over each sprocket and therollers on the end of an adjacent one of said armaandmeans mounted on the frame for swinging the. arms.

2. In combination-with apair of rear wheels of a vehicle, a frame and an axle housing; a

sprocket mounteddirectly on each of said wheels,

a bracket mounted on theaxle housing adjacent each sprocket,- an arm pivoted on each of said brackets, rollerson one end of eacharm', and each arm and the rollers thereon lying substantially in the plane of an adjacent wheel; a chain trained over each sprocket, and the rollers onthe end of an adjacent arm, means mounted on the frame for swinging the arms, and means incorporated in each arm whereby the. length thereof may be varied.r- Y ,7 3.-In -combination with a vehicular traction whe elandaxle. housing, of a sprocket mounted .directly on the wheel, a chain trained over said sprocket, andan' arm having a channel part pivotally mounted on said axle housing and a secondpartslidably engaged with said channel part,

rollers on one end of said second'part engaging said chain, and means connecting said parts of said arm for shifting said second part relative to th'echannel part and for securing it in adjusted position. v 1
